I thought I was going crazy, but finding this thread was helpful in seeing I hadn't. I posted postcards to the US from Edinburgh and Glasgow the first week of July '17 and only this week are people starting to receive them. Many are still missing. Way past the "up to six week" marker listed on the Royal Mail's rubric for international mail arrival dates. All postcards were redirected through the Philippines, and all with random black marker "censoring" parts of the messages I wrote or crossing out the name of the city or historic site that was printed on the card. (I.e. Tower of London had its "London" redacted.) Even a line I drew to separate the address from the message was "censored". Like the others on this post discussing arrival and censorship issues of postcards, I too used the beautiful souvenir stamps offered from the Tower of London gift shop and Scottish Trust gift shop in Edinburgh.
I am fully behind one poster's movement to complain to the Royal Mail. Also the English and Scottish Trusts need to be complained to. They are the ones hawking the stamps. They are most likely the root of the problem.
I have never had this issue before and I am furious. Personal messages have been tampered with by another government. Copyrighted material has been tampered with by another government. When I had the opportunity to be abroad a few years ago, I tried to be as diligent as possible about making sure all postcards I sent had "airmail" stickers or handwritten on the card, but there were times where I forgot. And they still got to the US within two weeks with no Philippines/redaction issues. I did forget the airmail stickers this time, but I'm not so sure that was the core of the problem. Heck, the letter my friend sent me from Australia several weeks after my UK trip didn't have "airmail" on it and it made it to me in the US in a week. And it was letter! I really think it's the souvenir shops's stamps that were the problem.
Anyway - thanks to the original poster and the list of respondents for making me feel more sane about this issue. I'm glad we're not alone. (Doesn't make this issue okay, but glad we're not alone. Our poor family and friends who have to receive our messages like this.)
